The evolution of sprayers

        Knapsack electric sprayer is a kind of plant protection machinery, which is widely used in agricultural plant protection operations.

        In the 1990s, the use rate of knapsack-type electric sprayers gradually increased, but because of their large shape, they not conducive to long-term operation. In 2005, the WH-5 type knapsack ultra-low-volume electric sprayer was born to avoid the disadvantages of the traditional knapsack electric sprayer. Its characteristics are:

        1. The appearance design is more novel: the overall design is more in line with people's traditional habits-the backpack style, the appearance is novel and generous, the structure is reasonable, the personality is outstanding, and the operation is simple.

        2. Large capacity of the liquid medicine bucket: The capacity of the liquid medicine bucket is 10 liters (10 kg), which can spray 3-5 acres (666.7 square meters/mu).

        3. Large spray volume: By adjusting the speed of the centrifuge and increasing the flow speed of the liquid medicine, the sprayed mist is more dense and dense. Therefore, the spray is more thoughtful and covers a wider area.

        4. Dual-purpose batteries are more convenient: on the basis of using four No. 1 batteries, a storage battery is also equipped as a power source. This storage battery is maintenance-free, large in capacity, and sufficient in power, and it is more labor-saving to use.
